← ScienceWhich outcome occurs when an MRI machine quenches?
A)Superconducting field collapses rapidly.✓
B)Magnetic field alignment increases
C)Cryogen pumps initiate cooling
D)Radio frequency emissions intensify
💡 Explanation
When an MRI machine quenches, a sudden loss of superconductivity occurs, resulting in extremely rapid resistive heating; this in turn triggers rapid Helium vaporization because the latent heat of vaporization is much lower than the heat produced, therefore, the superconducting field collapses rather than remaining stable.
